A hardware key is configured to be coupled to the meter via the second communication path defined by the hardware key interface. The data on the at least one memory device cannot be modified unless the hardware key interface is physically coupled to the hardware key. The hardware key may include a key code component and conducting lines, where the hardware key interface receives the key code via the conducting lines and the data on the at least one memory device cannot be modified unless the key code provided by the hardware key is validated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hardware key system for device protection","description":"A medical device includes at least one memory device storing data; a communication interface defining a first communication path to allow communications between the medical device and an external devi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11520890","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
